Resumo: | Crop demands for the macronutrient sulfur (S) are similar or greater than those for phosphorous. However, S is often overlooked in the management of crop fertilization. This study aimed to evaluate the effect of sources and doses of S on soybean cultivation under field conditions. A randomized block design, with 4 replications, was used. The treatments were arranged in a factorial scheme with one additional treatment (3 x 5 + 1), totaling 64 experimental units. Sources (elemental sulfur, single superphosphate and agricultural gypsum) and doses (20 kg ha-1, 40 kg ha-1, 60 kg ha-1, 80 kg ha-1 and 100 kg ha-1) of S were used, in addition to one control (without fertilizer). The following parameters were assessed: plant height at flowering, 1,000-seed weight, yield and agronomic efficiency, which were affected by the doses and sources of S; number of pods per plant, only affected by the sources of S; and number of pods with 3 seeds, with no statistical difference for any of the treatments. The highest yield recorded was 1,927 kg ha-1, at the dose of 80 kg ha-1 of S for gypsum, and the greatest agronomic efficiency was observed for the single superphosphate, at the dose of 20 kg ha-1 of S. |

Apesar disso, muitas vezes, o S não é incorporado ao manejo da adubação de culturas. Objetivou-se avaliar, em condições de campo, o efeito de fontes e doses de S na cultura da soja. O delineamento foi em blocos ao acaso, com 4 repetições. Os tratamentos foram dispostos em esquema fatorial com um tratamento adicional (3 x 5 + 1), totalizando 64 unidades experimentais. Foram utilizadas fontes (enxofre elementar, superfosfato simples e gesso agrícola) e doses (20 kg ha-1, 40 kg ha-1, 60 kg ha-1, 80 kg ha-1 e 100 kg ha-1) de S, mais um controle (sem fertilizante). Foram avaliados os seguintes parâmetros: altura da planta no florescimento, massa de 1.000 grãos, produtividade e eficiência agronômica, as quais foram influenciadas pelas doses e fontes de S; número de vagens por planta, que somente foi influenciado pelas fontes; e número de vagens com 3 grãos, que não se diferenciou estatisticamente em nenhum tratamento. A maior produtividade foi de 1.927 kg ha-1, na dose 80 kg ha-1 de S para o gesso, e a maior eficiência agronômica foi observada para o superfosfato simples, na dose de 20 kg ha-1 de S.Escola de Agronomia - Universidade Federal de Goiás2017-09-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/45394Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 3, Jul./Sep. 2017; 296-302Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 3, jul./set. 2017; 296-302Pesquisa Agropecuária Tropical; v. 47, n. 3, jul./set. 2017; 296-3021983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/45394/24318Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessLopes, Liliane OliveiraMoura, Márcio Clero Soares deMatias, Sammy Sidney RochaLopes, Ricardo dos SantosTeixeira, Marcos Paulo Rodrigues2020-07-13T18:44:12Zoai:ojs.revistas.ufg.br:article/45394Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:16.404570Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
